Silver Mining in History

By about 100 CE, the center of silver mining moved to Spain, where the mines became a major supplier for the Roman Empire and an essential trading component along the Asian spice routes. However, no other single event in silver''s history rivals the discovery by European conquerors of the white metal in the Americas following Columbus''s landing in the New World in 1492.

Precious Metal Refining Process | The Perth Mint

The electrolytic silver refining process is similar to gold, except that the silver anodes are dissolved in a bath of nitric acid. The resulting cathodes are 99.9% pure silver. As with small gold bar production, these cathodes are melted, granulated and cast into retail sized bars (most common being 100oz or kilo).
